Struct DigestHeader 

pub struct DigestHeader { /* private fields */ }

Header describing the digest that anchors a timestamp.

Implementations

impl DigestHeader

pub fn new<D: DigestOpExt>(digest: Output<D>) -> Self

Creates a new digest header from the given digest output.

pub fn kind(&self) -> DigestOp

Returns the digest opcode recorded in the header.

pub fn digest(&self) -> &[u8]

Returns the digest bytes trimmed to the opcode’s output size.

Trait Implementations

impl Clone for DigestHeader

fn clone(&self) -> DigestHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DigestHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<A: Allocator> DecodeIn<A> for DigestHeader

fn decode_in( decoder: &mut impl Decoder, _alloc: A, ) -> Result<DigestHeader, DecodeError>

See Decode::decode for details.

fn decode_trailing( decoder: &mut impl Decoder, alloc: A, ) -> Result<Option<Self>, DecodeError>

See Decode::decode_trailing for details and caveats.

impl Default for DigestHeader

fn default() -> DigestHeader

Returns the “default value” for a type.

impl Display for DigestHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encode for DigestHeader

fn encode(&self, encoder: &mut impl Encoder) -> Result<(), EncodeError>

impl Hash for DigestHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DigestHeader

fn cmp(&self, other: &DigestHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DigestHeader

fn eq(&self, other: &DigestHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DigestHeader

fn partial_cmp(&self, other: &DigestHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
